Hello!
We are using JIRA as a Customer Service Desk. External users need to be invited into the project or they can Sign Up before creating the ticket via a Form.
Question that has risen is that we have a lot (~100) of clients who have been added to the project and are using it Daily, however a few clients (around 10) are displayed in the "People" tab of the project settings. I have added a picture below of one of the customers.
The questions are:
a) Why are some customers displayed in this view?
b) What are the implications on removing them from this list?
c) Why aren't all of the external users here - where is the logic?
d) Why are there people in this list (also internal) who do not have an email in display - are they not actively using this and can they be removed?
e) Are all People here counted as "USERS" for the billing of service?

Thanks a lot for your help!
Best,
Andres
